The 'Rock the Kasbah' actor also donned a Make America Great Again cap during his interview with Jimmy Fallon.

The actor, who is starring in the upcoming Rock the Kasbah and is in his first Broadway play Misery, was greeted by the late-night host with compliments on his looks, which closely resembled GOP candidate Donald Trump.

Donning a blond, slick-back wig, blue suit and red tie, Willis gave the cameras a presidential wave and an "I like that guy" while pointing a finger to an audience member.

"What's going on with the hair?" Jimmy Fallon asked the actor. "It suddenly has just seemed to grow exponentially, and I was a blond when I was a kid," explained Willis, who is notoriously known to be bald in his film roles.

"My hair — it's normal," Willis said, explaining that he'll start off with hair and shave it down. "This is it," he said in response to Fallon asking what it would look like if he let it grow.

The late-night host brought out photos of the actor in Armageddon, Die Hard and Pulp Fiction (as well as a photo of the baby, who he voiced, in Look Who's Talking) that had Trump's Photoshopped hairdo on the actor's head. They also showed a clip from The Sixth Sense, in which Willis had a superimposed wig on his head.

Willis said he plays a character "that just can't stop killing" in the comedic action film Rock the Kasbah, before bringing out a red Trump hat that read Make America Great Again to stop Fallon from being distracted by "his" hair. "That's Bruce Willis. That's what I'm talking about. Much better now. Now I know who you are. I love all your stuff," Fallon joked when Willis put on the cap.

"How exactly do you comb it?" Fallon jokingly asked Willis of his hair. "Right to left," Willis said gesturing. "Depending on the wind, really it just handles itself." He said that the product in his hair is "sand, beach sand." Willis explained, "that's how I keep this shape. It's like a dune and a little water slide in the back."
